ELMONT — A 911 call about a teen possibly carrying a gun forced a Long Island high school into lockdown for several hours on Tuesday before authorities gave the all-clear. An air-powered toy gun was later found in a student's locker, police said.

Officers, including a SWAT team, responded to Elmont Memorial High School after a woman told authorities she saw what might have been a lime green gun inside a teen's backpack at the school, said Inspector Kenneth Lack, a Nassau County police spokesman. The call came in at around 7:45 a.m., about 10 minutes before classes began, and the school went on lockdown shortly after that.

Police searched three floors, room by room, before determining the school was safe. The lockdown was lifted shortly before 1 p.m. Police later said in a news release that a toy lime green Nerf lever-action gun was found in a student's locker. No arrests were made.
